SPANTREE Messages

This section contains the spanning-tree messages.

Error Message SPANTREE-2-BLOCK_BPDUGUARD: Received BPDU on port [chars] with BPDU

Guard enabled. Disabling port.

Explanation

A bridge protocol data unit (BPDU) was received on an interface that has the spanning

tree BPDU guard feature enabled. As a result, the interface was administratively shut down. [chars]

is the interface name.

Recommended Action Either remove the device sending BPDUs, or disable the BPDU guard feature.

The BPDU guard feature can be locally configured on the interface or globally configured on all

ports that have PortFast enabled. To disable BPDU guard on an interface, use the no spanning-tree

bpduguard enable interface configuration command. To disable BPDU guard globally, use the no

spanning-tree portfast bpduguard default global configuration command. After you have

removed the device or disabled BPDU guard, re-enable the interface by entering the no shutdown

interface configuration command.
